* RouterModule can be imported multiple times: once per lazily-loaded bundle.
|
||
* Since the router deals with a global shared resource--location, we cannot have
|
||
* more than one router service active.
|
||
*
|
||
* That is why there are two ways to create the module: `RouterModule.forRoot` and
|
||
* `RouterModule.forChild`.
|
||
*
|
||
* * `forRoot` creates a module that contains all the directives, the given routes, and the router
|
||
* service itself.
|
||
* * `forChild` creates a module that contains all the directives and the given routes, but does not
|
||
* include the router service.
|
||
*
|
||
* When registered at the root, the module should be used as follows
|
||
*
|
||
* ```
|
||
* @NgModule({
|
||
* imports: [RouterModule.forRoot(ROUTES)]
|
||
* })
|
||
* class MyNgModule {}
|
||
* ```
|
||
*
|
||
* For submodules and lazy loaded submodules the module should be used as follows:
|
||
*
|
||
* ```
|
||
* @NgModule({
|

|

*
|
||
* Managing state transitions is one of the hardest parts of building applications. This is
|
||
* especially true on the web, where you also need to ensure that the state is reflected in the URL.
|
||
* In addition, we often want to split applications into multiple bundles and load them on demand.
|
||
* Doing this transparently is not trivial.
|
||
*
|
||
* The Angular router solves these problems. Using the router, you can declaratively specify
|
||
* application states, manage state transitions while taking care of the URL, and load bundles on
|
||
* demand.
|
||
*
